iPhone Device Could Prevent Strokes

Researchers at the University of Sydney have developed an iPhone app and case which measures heart rhythm, and may help aged care workers across the country to prevent strokes and heart problems in residents. Senior author of the study and Professor of Cardiology at Concord Hospital and the University of Sydney Ben Freedman, said he believed that the device and application would help those who work in aged care.

The AliveCor Hearth Monitor for iPhone (iECG) is an app with a single-lead ECG taken on an iPhone with a special case, which can take a reading in real time on an iPhone screen. The iECG is then transmitted to a secure service where a specialist can review the iECG’s remotely.The device is able to discover if a patient has any undiagnosed atrial fibrillation (AF) which is a common heart rhythm problem and is responsible for almost one third of strokes, however those with AF can reduce their risk of stroke by 66 per cent by taking correct medication.

“I think it’s going to be more useful for people who work in aged care although some individuals will be able to use it” he said.

The test is able to be used in local pharmacies and general practitioner offices and Mr Freedman said he expected an RN in an aged care facility would easily be able to use it.

“We are currently conducting a trial where the secretary or receptionist at a GP’s office can do it, since it doesn’t require any real training” he said.

The researchers discovered that about 1.4 per cent of the population over 65 (50,000 Australians) had AF but were not aware of it.

Lead author of the study Nicole Lowres said the knowledge gap of patients with AF was surprising and alarming.

“Over half of those with known atrial fibrillation in AF at the time of screening were unaware of their diagnosis even though they were prescribed and taking warfarin (a common medication to treat AF) to treat their condition” she said.
